Introduction

After ordering my package from Amazon.com.au it arrived 3 business days later. It maybe different from where you purchase the item.
I opened the package to reveal that the condition was excellent.

Condition


Well packed with foam padding to protect the pins.

Inside of a sealed Anti-static bag.

Listing

The listing on Amazon.com.au indicated that it was a NodeMCU board one of the advantages of using this is that it is well supported. Lots of documentation, circuit diagrams, pinouts etc.


It is mentioned in the listing
Please Kindly Note:
This board has no pin labeling on the top side.

Inspection

Breadboard friendly: Yes when placed on a prototype board it leaves one pin free on either side of the dev board, however, there is no pin labeling on the top of the board which is mentioned in the sellers description.



close examination of the board revealed no errors and is a clean board.

Installing CH340 / CH341 drivers for Arduino, ESP32 and ESP8266 boards. Introduction With the development of Arduino, ESP32 and ESP8266 boards there has been a requirement to communicate to these devices via USB. There are several of these components or Integrated Circuits (IC) available that are installed on development boards. In order to communicate to these boards with Arduino IDE or other IDEs there is a requirement to install specific drivers. Procedures Close Arduino IDE Mac Download and install drivers from here After installing the drivers the computer is required to be restarted for the drivers to function. To confirm drivers are working correctly connect device goto terminal type ls -l /dev/tty.* the device will be displayed in the list as shown in the Figure 1 Figure 1 - list of devices Caution OSX Sierra (10.12) users It has been reported the driver WILL crash on OSX Sierra. Make sure to use this one instead: ch340 v1.3 driver For fur...
